Pro Tip
Backup Frequency
For critical data, implement a 3-2-1 backup strategy: 3 copies, 2 different media, 1 offsite location. This protects against hardware failure, local disasters, and ransomware attacks.
Gold Rule
Backup Validation
Always verify backups by restoring a test file. A backup that hasn't been tested is no backup at all.
Word Origin
数据 (shùjù) = data; 备份 (bèifèn) = backup. The term combines two Chinese words where 备份 originally means 'to prepare a secondary copy' (from 备 'prepare' + 分 'divide'). The compound emerged in the digital age to describe the technical process of copying data.
Usage Notes
In Chinese IT contexts, 数据备份 is the standard term for the process. The verb form '备份数据' (to back up data) is also common. Avoid literal translations like 'data copy' unless referring to a specific type of backup.
